Abstract
Disclosed is a Brillouin erbium-fiber laser system producing multiwavelengths with a dual spacing of 10 GHz and 20 GHz. The Brillouin erbium-fiber laser system includes: a Sagnac reflector generating even- and odd-order Strokes waves by launching input lights, a first unit forming a first resonator with the Sagnac reflector, wherein the first unit is coupled to a first directional coupler in the Sagnac reflector, a second unit forming a second resonator with the Sagnac reflector, wherein the second unit is coupled to the first directional coupler in the Sagnac reflector, and a third unit for inputting Brillouin pump light into one of first and the second units, whereby the optical fiber laser system outputs multiwavelengths with a dual spacing.
